One end of the second heat conduction pipe 11 extends to the outside through the switching box 17 and the coating trough 5 and is connected to a cold liquid outlet pipe.

[0019] The shape of the first heat conducting pipe 27 matches the inner cavity of the stirring rod 26 . The first heat conducting pipe 27 and the stirring rod 26 are connected via a fixing block 28 , so that the stirring rod 26 can be heated evenly.

[0020] The transmission assembly includes a driving gear and a driven gear. The driving gear is fixed to the driving end of the drive motor 3, and the driven gear is fixed to the top of the stirring rod 26. The driven gear is meshed with the driving gear to drive the stirring rod 26 to rotate.

[0021] The mobile mixing mechanism includes a rotating tube 13 rotatably connected to the inside of the coating tank 5, the second heat conducting tube 11 passes through the inside of the rotating tube 13, and the surface of the second heat conducting tube 11 located inside the rotating tube 13 is provided with an external thread 22, and the external thread 22 is connected to a thread block 24. Stirring blades 16 are provided on both sides of the rotating tube 13, and a strip-shaped opening 23 is opened on the surface of the rotating tube 13. One end of the stirring blade 16 passes through the strip opening 23 and is connected to the thread block 24. The stirring blade 16 can be heated by heat conduction, thereby maintaining the temperature inside the coating tank 5 during back and forth stirring, increasing the fluidity of the gel fragrance, and avoiding precipitation.

[0022] One end of the rotating tube 13 extends to the interior of the switching box 17. The outer surface of the rotating tube 13 is sleeved with a first driven bevel gear 29 and a second driven bevel gear 31. The first driven bevel gear 29 and the second driven bevel gear 31 are both rotatably connected to the inner wall of the switching box 17.

After reversing, the fragrance-imparting electric coating roller 7 can drive the rotating tube 13 to rotate in a linked manner without the need for additional kinetic energy, which is more energy-saving.

[0025] Working principle: When in use, first pour the gel mixed essence into the mixing box 1, and hot water enters from the hot liquid inlet pipe 25, reaches the inside of the stirring rod 26 and heats it while stirring to increase fluidity. After the mixing is completed, the gel fragrance is sent into the coating tank 5 through the liquid pump. When the fragrance electric coating roller 7 rotates, the gel fragrance can be brought out, and then it contacts the conveyed PLA film and is coated on its surface, thereby achieving the fragrance of the PLA film. When the fragrance electric coating roller 7 rotates, the linkage mechanism drives the active bevel gear 30 to rotate, and the active bevel gear 30 drives the first driven bevel gear 2 9 rotates, thereby driving the rotating tube 13 to rotate in the forward direction. When the rotating tube 13 rotates, the stirring blade 16 can be toggled to rotate and move, and at the same time drive the contact plate 21 to move. When the contact plate 21 contacts the first contact switch 14, the first electromagnet 18 is de-energized and the second electromagnet 20 is energized, so that the slide rod 19 drives the reversing sleeve 32 to contact the second driven bevel gear 31, thereby driving the rotating tube 13 to rotate in the reverse direction. This reciprocating process realizes back and forth stirring. At the same time, the hot water will pass through the second heat-conducting tube 11 and transfer its temperature to the stirring blade 16 so that it maintains the temperature of the gel fragrance during rotation, thereby increasing fluidity.
